Mandevilla plant named ‘Sunparaosto’

ABSTRACT

A new and distinct cultivar of  Mandevilla  plant named ‘Sunparaosto’, characterized by its vining plant habit; vigorous growth habit; freely branching habit; dark green-colored leaves; freely flowering habit; long flowering period; and bright rose red-colored flowers.

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘SUNPARAOSTO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla hybrida and hereinafter referred to by the name ‘Sunparaosto’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new vining Mandevilla plants with numerous large attractive flowers.

The new Mandevilla plant originated from a cross-pollination in Higashiomi, Shiga, Japan in June, 2009 of a proprietary selection of Mandevilla hybrida identified as code number 02M-511, not patented, as the female, or seed parent with a proprietary selection of Mandevilla hybrida identified as code number 06M11-4, not patented, as the male, or pollen, parent. The new Mandevilla plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in November, 2010.

Asexual reproduction of the new Mandevilla plant by cuttings in Higashiomi, Shiga, Japan since November, 2010 has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunparaosto’. These characteristics in combination distinguish ‘Sunparaosto’ as a new and distinct Mandevilla plant:

-   -   1. Vining plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Dark green-colored leaves.     -   5. Freely flowering habit.     -   6. Long flowering period.     -   7. Bright rose red-colored flowers.

Plants of the new Mandevilla can be compared to plants of the female parent selection. Plants of the new Mandevilla differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla have smaller leaves than plants         of the female parent selection.     -   2. Plants of the new Mandevilla have smaller flowers than plants         of the female parent selection.     -   3. Plants of the new Mandevilla and the female parent selection         differ in flower color as plants of the female parent selection         have red-colored flowers.

Plants of the new Mandevilla can be compared to plants of the male parent selection. Plants of the new Mandevilla differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla have larger leaves than plants         of the male parent selection.     -   2. Plants of the new Mandevilla and the male parent selection         differ in flower color as plants of the male parent selection         have pink-colored flowers.

Plants of the new Mandevilla can be compared to plants of the Mandevilla hybrida ‘Sunparaoros’, disclosed in U.S. Plant Pat. No. 25,207. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Mandevilla differed from plants of ‘Sunparaoros’ in the following characteristics:

-   -   1. Plants of the new Mandevilla had longer lateral branches with         longer internodes than plants of ‘Sunparaoros’.     -   2. Plants of the new Mandevilla had smaller leaves than plants         of ‘Sunparaoros’.     -   3. Plants of the new Mandevilla and ‘Sunparaoros’ differed in         flower color as plants of ‘Sunparaoros’ had bright red-colored         flowers.     -   4. Plants of the new Mandevilla had shorter peduncles than         plants of ‘Sunparaoros’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late summer in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Mandevilla production.
